介绍了利用遥感资料得到的海表温度(SST)图估算海表流场的最大相关系数法和相关松弛法.比较二种方法在不同参数条件下的矢量图,相关松弛法明显地优于最大相关系数法.在用相关松弛法时,模板大小和搜索距离这二个参数对计算结果影响很大,选择16×16像元数的模板和15像元数的搜索距离计算1989年12月3日～12月6日台湾海峡这一组资料时比较理想,结果表明用相关松弛法计算海表流场有一定的可靠性和实用性.
The maximum correlation coefficient method and the correlation relaxation method for estimating the sea surface flow field using the SST data obtained from the remote sensing data are introduced.Comparing the vector diagrams of the two methods under different parameters, the correlation relaxation method is obviously better than the maximum Correlation coefficient method.Using the correlation relaxation method, the template size and the search distance of the two parameters of the calculation results have a great influence on the choice of 16 × 16 number of pixels template and 15 pixel search distance calculation December 1989 3 The data from Day to December 6 in the Taiwan Strait are ideal, and the results show that the correlation relaxation method can be used to calculate the reliability and practicability of the sea surface flow field.
